Combined removal of inorganic contaminants from a synthetic stormwater was investigated by their sorption on hydrous ferric oxide (HFO) (5%), HFO+Ca(OH)(2)(6%), and HFO+Ca(OH)(2)+MnO2 (7%) in columns containing 93-95% anthracite, conducted under seven intermittent runoffs, each of 8 h duration with a 40 h (drying) period between them. At the initial period when Ca(OH)(2) produced elevated pHs, the HFO column removed less metals but more Se than the HFO+Ca(OH)(2) columns. With increased time when the pH effect of Ca(OH)(2) became insignificant, the MnO2 in the column increased the removal of all contaminants. The removal efficiencies (%) at the flow rate of 0.75 m/h for Cd, Cu, Ni, Zn by the HFO+Ca(OH)(2)+MnO2 column were 88-100%, and Se by the HFO column were 92-94% for the 1st and 3rd runs. The corresponding values for the 5th and 7th runs were 51-88% and 82-88%, respectively.
